Quicrun ESC issues

[Brady Matthews]

I have a Hobbywing Quicrun 10BL120 censored ESC in my rock bouncer and I shut it off one day and this morning it was beeping and the throttle didn't work. Fully charged battery too. Anyone know what might have caused this?

Is the set button stuck on? Kinda sounds like it’s cycling through the programming options

I thought about that, but it doesn't seem to be stuck

Have you check the wiring between switch and esc to make sure they ain’t pinched and shorting together somewhere?

It does not seem to be pinched or shorting

Well dang. I know what I’d do next but you better off waiting for some other ideas

Do you have a programmer card?
I had a weird thing happen with a Spektrum esc red light of death....
Plugged in card and it just stopped blinking and worked fine. No idea what that was about!

Just to make sure, is your throttle trim at zero? It needs to be at zero when you turn the truck on. Turn it there, and glue it It's not needed on an electric RC.

I do have one, I just need to find it

It's at zero

Does your switch unplug? I thought some HW offered that but I'm new to HW... Don't go yanking TOO hard and MAKE the switch come off!
Thought if its defective or got wet... easy test?

It doesn't unplug from the ESC

My next thought was to snip the signal wire for the set switch between esc n switch. The beep and flashes in video seem to correspond with the manual like it’s cycling through but I don’t know for sure. I would snip in a place easy to solder back together and if the problem does go away replacement switches are available

I also feel like it is counting, and in a program mode

I was thinking the same thing

Watching the video, it could very well be as simple as a sticky switch. I am amazed at how much knowledge this @Lostinthewoods86 guy has acquired in such a short time in the hobby. He can't even find his way home, yet he can build and diagnose RC cars
